I am perfectly fine selling SONOS as a music solution even if it is not tied into the control system. Having it in the same app as your cameras and hvac is not that critical unless you sell it as such. Our younger clientele are much less concerned about having all their subsystems controlled by a single UI or app that only gives them partial control and/or feedback compared to what the native apps give them.
Exciting times for sure.
